You're going to spin better on Gold Seals, they have a higher heel stancion so you feel on an incline in a way.I feel like a lot of it has to do with anatomy for sure. I am in Jacksons and have skated with both coronation aces and gold seals. I had great issue with spinning consistently on the coronation aces however when I swapped over to gold seals everything seemed to just click almost in an instant. That and certain turns definitely became easier mainly twizzles and loops which is apparently very counterintuitive considering coro's are rounder blades but I found the blade being flatter added a stability when doing the above.
